  3. colour through thin films

  4. dispersion of white light into colours

Show answer
Correct Option: B
Explanation:

Rectilinear propagation of light.
According to Newton’s Corpuscular Theory of Light, light consists of very tiny particles called corpuscles. These corpuscles, on emission from the source of light, travel in straight line with high velocity.

The size of corpuscles are ________ for different colours.

  1. same

  2. different

  3. either (a) or (b)

  4. None of these

Show answer
Correct Option: B
Explanation:

Different.
The corpuscles can be of different sizes. The different colors of light are due to the different sizes of the corpuscles.

According to corpuscular theory, the velocity of light in the denser medium is greater than that in rarer medium.

evs magic with mirrors dual nature of light nature and sources of light theories on light

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

The corpuscles (light) would travel faster in the denser medium than in rarer medium. But later this is proved wrong. We know that light travels faster in the rarer medium than in denser medium.
